A nuclear power plant reactor that was damaged by the 2011 earthquake and tsunami disaster and idled under stricter safety standards following the Fukushima crisis won approval from the nuclear watchdog on Wednesday for operations to resume.
The No. 2 unit of Tohoku Electric Power Co.'s Onagawa plant in Miyagi Prefecture received the green light after the addition of disaster prevention measures, including a towering seawall that is nearing completion.
The approval, given in a unanimous vote, was the first to be secured by the operator under the revised standards. The reactor is only the second of those damaged in the March 2011 calamity to clear the Nuclear Regulation Authority's new safety regulations, after the Tokai No. 2 power station in Ibaraki Prefecture.
